Too skinny - if/when it becomes unhealthy psychologically and/or physically, then yes, one can be too skinny.
For example, if one is thin and it's just her body type, and she is otherwise healthy, but she just looks bony, then she's not too skinny. If one is thin, but she has a mental abhorration to food and collapses during ballet class because of malnutrition, then yes, she is too skinny.
What is too skinny? Nicole Richie. I loved Nicole with a little, HEALTHY fat on her!

I have NEVER met Cheyenne Jackson. I have never hung out with him in his dressing room, he did not tweet me, he never bought me a beverage, and he mostly certainly didn't tickle me. . .that is all.
